NBC’s Luke Russert was dashing in white at the Fifth Annual Winter Ball in support of Children’s Hospital Boston on Saturday night. Russert (right) told our photographer that he hadn’t planned on wearing white to the affair. He left his own suit in a taxi and then ran to a nearby clothing store to replace it. The white ensemble was the only thing that fit him on the spot. Joining Russert during the night were (from left) Tom Greeley and Chelsea Rader, of Boston, and Tori Lewis of Washington, D.C.
